We recently encountered an issue where appointments (not meetings) appear in Notes client calendars, but not in their iOS device calendars. All other types of calendar entries sync just fine between Traveler and iOS.
For step 4, recreation, please create a new appointment with a unique subject ( ie IBM TEST Appointment 1 ) and wait 10 to 15 minutes
before collecting logs using the tell traveler -s pmr command. Before collecting the logs, generate a dumpdoc of the new appointment.
Note if the user’s mail DB is encrypted, the dumpdoc will not be accessible by support, in this case, a new empty DB should be created without
encryption and then cut and paste the appointment to the new database before uploading to IBM.
We are experiencing exactly the same issues and it seems to have started within the last 2 weeks. Alos iOS 9 and Traveler 9.0.1.9, though we experienced the same on 9.0.1.1 Please keep us posted with the results.
